I am trying to use MAGMA to calculate the inverse of a matrix (not to solve a linear system), but I had problems when my test matrix had N=3052.

As I am running on a GeForce GTX590, the sizes in testing_zgetri_gpu.cpp don't fit in my GPU's memory, so I modified the sizes array to run from N=3000 to N=3100 with steps of 10. The results of the tests are:
